Accuracy Assessment of LIDAR Data Using Longitudinal Profile of a Road

Abstract

LiDAR data gives accurate elevation therefore; we can obtain 3Dmodelling from LiDAR data which can be used for many applications such as civilengineering and surveying engineering, etc.For accuracy assessment of LiDAR elevation data, a longitudinal profile are donefrom field survey using laser level instrument type (Leica Sprinter 100) of a roadhaving about (350m) length, adjacent to the Building and ConstructionEngineering Department, which locates inside study area, then compares it withlongitudinal profile, which drowns from LiDAR elevation data using (ArcGIS9.3)program. According to the results analysis it can be stated that the elevations fromthe LiDAR data within accuracy of (3-10) cm can be obtained.
